“…However, using biodegradable materials presents a significant challenge in soft robot design because biodegradable materials typically have weaker mechanical properties while soft robots require high resilience to withstand stress and deformation [72]. Textile made of mixed cellulose nanofibers exhibits excellent toughness, and can quickly degrade in seawater, making it a good candidate for watercraft equipment [73]. Using biodegradable materials offers a significant advantage in reducing environmental pollution.…”

Soft robotics possesses expansive utilization prospects in various domains, including medical aid, interior services, food and agriculture, and even space exploration. However, due to the limitations presented by the volume and weight of the driving, sensing and control systems, many soft robots are forced to rely on electrical or pneumatic tethers to transmit signals and supply energy, restricting their adaptability to structured environments. Fortunately, advancements in soft robotics have addressed this issue by integrating separate systems into a whole, achieving controllable and predictable autonomous motion. This paper reviews current integrated soft robots from bionic-inspired and function-oriented design inspirations, as well as their application perspectives. Integrated electrical, chemical, pneumatic and mechanical systems present numerous integrated design challenges and, therefore, reliable solutions to facilitate integration and intelligence are summarized herein from the perspectives of materials, fabrication, power source, sensing and control. Lastly, we discuss the potential of machine learning in solving current problems faced by soft robots and improving their behavioral intelligence.

“…11,12 The literature reports that the combination of natural nanoparticles with polymers derived from biomass wastes drive the fabrication of biocomposite materials with thermomechanical properties comparable to petroleum-based plastics. [13][14][15] Biobased composite materials are suitable for several purposes depending on their specific functionalities. As examples, composite films based on halloysite clay nanotubes and funori recovered from red seaweed Gloiopeltis were successfully employed for the controlled release of sodium diclofenac.…”

Microscopic electromechanical response of a poly (3-hydroxybutyrate-co-3-hydroxyhexanote) (PHBH) fiber, a polymer more biodegradable than poly (lactic acid) (PLA), are observed. The crystallization of PHBH fibers is enhanced by the annealing, and a strong electromechanical response is observed in the particles. Different positive and negative electromechanical responses are observed within a single PHBH fiber particle by lateral piezoresponse force microscopy. The electromechanical response of PHBH fiber is suggested to be due to shear piezoelectricity, since the molecular chain of PHBH fiber has a helical structure similar to that of PLA and cellulose. In addition, the deformation is confirmed to be a displacement corresponding to particles of 100 ~ 300 nm in diameter.
